3 Definition of terms, symbols and abbreviations
3.1 Terms
For the purposes of the present document, the following terms apply:
binocular parallax: disparity between the two retinal images of a three-dimensional object or scene arising from the
slightly different vantage points of the two eyes, such binocular disparity functioning as one of the binocular cues of
visual depth perception and providing the basis for stereopsis
NOTE: As defined in https://www.oxfordreference.com/.
ETSI
9 ETSI GR F5G 020 V1.1.1 (2024-06)
motion parallax/moving parallax: monocular depth cue arising from the relative velocities of objects moving across
the retinae of a moving person
NOTE: The term parallax refers to a change in position. Thus, motion parallax is a change in position caused by
the movement of the viewer. Motion parallax arises from the motion of the observer in the environment.

4 Categorization of use cases
4.1 F5G Advanced Key Focus
As described in ETSI GR F5G 021 [i.1], the main business needs identified by F5G Advanced are outlined in Figure 1.
They improve various dimensions over previous generations of fixed networks.
Networks Service Management
a) Speed and Capacity (bandwidth)
e) Reliability h) Operational Efficiency
b) Coverage (connectivity)
f) Availability i) Energy Efficiency
c) Responsivity (Latency)
g) Security j) Spectral Efficiency
d) Density
Figure 1: Key Focus for F5G Advanced in the categories of Network, Service, and Management
In the present document, there are seventeen use cases described, which take advantage of the key technical
characteristics defined for the F5G-A network. Each use case may demand a different subset of the 10 high level
categories depicted in Figure 1. With further research, subsequent use cases may be specified.
4.2 Driving the characteristics of F5G Advanced
The use cases as described in the present document are driving the six characteristic dimensions that are specified in the
document on generation definitions ETSI GR F5G 021 [i.1], namely enhanced Fixed Broadband (eFBB), Real time
Resilience Link (RRL), Guaranteed Reliable Experience (GRE), Optical Sensing and Visualization (OSV), Full-Fibre
Connection (FFC), and Green Agile Optical network (GAO).
Figure 2 shows that:
• Depending on the use case, one or more dimensions are particularly important.
• All dimensions of the F5G-A system architecture are implemented by the following use cases.

4.3 Paving the Way for Fibre to Everywhere and Everything
F5G-A is leveraging technologies of fibre optical networks to benefit multiple segments including residential
applications, enterprise applications, network internal topics such as network optimizations plus the use of F5G-A for
the mobile infrastructure and service convergence, and finally vertical industries-oriented use cases.
Figure 3 shows the different high-level segments where fibre to everywhere is applicable. The larger circle named
network features focus on optimization of the networking technologies.
In the present document, the aspects of mobile have a limited number of use cases assigned to it. Future use cases might
add more mobile oriented aspects.

b) Key segment and business area addressed.
c) Key focus of the use case - new or enhanced services, network infrastructure and service features or in network

5.1 F5G-A Use case #1: Premium private line service
automation
5.1.1 Use case context
Traditional OTN-based premium private line services have the characteristics of high bandwidth, ultra-low and
deterministic latency, availability and security, and are widely used in many scenarios such as government institutions,
financial organizations, medical organizations and large enterprises (see Use Case #2 and #16 in ETSI
GR F5G 008 [i.2]).
As F5G evolves to F5G-A, new applications such as Business to Business (B2B) high-speed transport, 5G, Virtual
Reality (VR) and Cloud Data Centre are rapidly developing, which leads to the emergence of a variety of new
application scenarios. These new applications will need different and higher network performance from the operators'
premium private line services.
To keep up with the changing application needs and take advantage of the business opportunities, the network operators
need to enable fast rollout and provisioning of premium private line services. To achieve these improvements, the
premium private line service has to provide a higher degree of automation, with the improvement of self-service,
on-demand provisioning, high agility and flexibility.
